Eric, way back when, I bought a relatively early, new Farmington (serial number R 43x). I sent it back to you to correct a feeding problem. You replaced the slide with one marked Deer Park in block letters, and “Made in U.S.A”. I am now retired and selling off many of my firearms. I am considering selling the R9 and want to be able to explain to a potential buyer the slide change. Figured your explanation would be the most authoritative. Thanks!
